Apache Doris
Apache Doris ships its own MCP server as a Python service that connects to Doris over the MySQL protocol and serves tools over stdio, SSE or streamable HTTP. Version 1.0 replaced a large flat tool list with eight stable domains and progressively disclosed child capabilities — a deliberate answer to the context-window problem that large tool surfaces create. The exposed capabilities are read-only, covering catalog inspection, query execution, cluster monitoring, asset search and governance. Apache 2.0, in the separate apache/doris-mcp-server repository.
